Description
In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: Fix crash when adding interface under a lag Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag") fixed a similar issue in the lan966x driver caused by a NULL pointer dereference. The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic and is susceptible to the same crash. This issue specifically affects the ocelot_vsc7514.c frontend, which leaves unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as it uses the DSA framework which registers all ports. Fix this by checking if the port pointer is valid before accessing it.

Executive Summary

This vulnerability is a crash issue in the Linux kernel's mscc ocelot driver. It occurs when adding an interface under a link aggregation group (lag) due to the ocelot_set_aggr_pgids() function accessing NULL pointers for unused ports in the ocelot_vsc7514.c frontend. This leads to a kernel crash because the code does not properly check if the port pointer is valid before using it.

Impact Analysis

This vulnerability can cause the Linux kernel to crash when adding an interface under a lag in systems using the affected mscc ocelot driver. Such crashes can lead to system instability, downtime, and potential disruption of network services relying on the affected hardware and driver.

Mitigation Strategies

To mitigate this vulnerability, update the Linux kernel to a version that includes the fix for the ocelot driver crash when adding an interface under a lag. The fix involves checking the validity of port pointers before accessing them, preventing NULL pointer dereference crashes.
